    Coprocessor driver ASUS M3N78-EM


    Hi, I just installed Windows 8. I installed display drivers, motherboard drivers, realtek drivers (sound), but in the device manager there's still coprocessor without drivers. I didn't update Win, maybe that's the problem?
    Thanx in advance

    Your mobo doesn't support Win 8. The missing driver is a Nvidia driver. I can't find a Win8 version. You can try downloading and installing the latest Win 7 (WHQL) chipset driver package (Beta 15.49) for your mobo here: M3N78-EM - Motherboards - ASUS

    Have you searched by the Hardware ID ?

    Search here: PCI Vendor and Device Lists
    Using this tutorial: Hardware Identification - Windows 7 Help Forums

    Basically, you use device manager to find the hardware ID of the unknown device(s) and search the database to find what device that ID refers to. You then have a much better idea of what the hardware is than "Coprocessor."

    It appears to be this:
    Device ID Chip Description Vendor Id Vendor Name
    0x0753 NVIDIA nForce System Management Controller 0x10DE NVIDIA Corporation
    Thanx anxsds, I'll look into this further, and see what I can do

    Hmm... I've installed the driver manually from device manager by looking for the driver in c:/NVIDIA/nForceWinVista64/15.49/English/SMU. Maybe it's was just the problem with installer, since it's for win vista/7.
    I'll mark this as solved.

    That's how I tend to do it as well - saves installing all of the potentially unnecessary stuff. I have the M3N78-VM and that driver is always missing in Windows 7 on a new install too. I've only had Windows 8 on that machine once, briefly (use the license on my laptop instead now) but I installed the Windows 7 driver and it seemed fine.
